Specification of Letters Patent.

Application filed .Tune 17, 1920. Serial No. 389,616.

To all whom it may concern:

Be it known that I, ROLAND P. BERNAR;

DINI, a citizen of the United States, residing at Lakewood, city ofCranston, in the county of Providence and State of Rhode Island, haveinvented certain new and useful Improvements in carbureter-Locks, ofwhich the following is a specification. This invention relates to acarbureter-c for motor vehicles, and the object of this invention is toprovide simple and effective means for looking a carbureter in closedposition so that the motor cannot be an unauthorized person.

The nature and advantages of the invention will be better understoodwhen the following detailed description is taken in connection with theaccompanying drawings,-

the invention residing in the combination and arrangement of parts'asclaimed.

In the drawings forming part of this specification, like numerals ofreference indicate similar parts in the several views and wherein: w

Figure 1 is a side elevation illustrating my improved locking deviceasattached to a motor vehicle, when positioned to be lowered to lock thecarbureter lever when in closed position.

Fig. 2 is a plan View illustrating the carbureter-locking mechanism.

Fig. 3 is a perspective view illustrating the stop member as engagingthe carbureter operating lever and the screw by which this" stop memberis actuated.

With reference to thedrawings, 1O designates the usual carbureter whichis attached to a motor, illustrated by dotted lines at 11. Carburetersof this character are usually provided with a so-called butterfly ordisk valve 12 which controls the passage of the carbureted vapor fromthe carbureter into the intake manifold 13, and this valve is operatedby means of a lever 14 through the rod 15 by vehicle dash 16.

Applicant-has provided a simple and effective means for engaging andlocking the valve-operating lever in closed position, which meanscomprises a frame 17 in which is mounted a vertically-disposed screw 18threaded through a carrying-plate 19, one end of which plate is forkedas at 20 to slide on said frame as the screw is rotated.

On this plate 19 I have mounted an arm 21 adapted to be adjusted.longitudinally started by hicle.

means, not shown, from the.

operated by'an unauthorized person, I have also provided a casing 39about this key, the-- by the lock 40,-

whereby when it is desired thereon so as to regulate its projectinglength.

This arm 21 has a downwardly-extending end portion 22 to which is fixeda stop boss 23 adapted to fit over and engage the valve lever 14 to lockit ii closed position when the screw 18 is actuated to move the samedownwardly, lease thislever the stop may be raised from engagement byturning the screw in the opposite direction.

In order to operate this locking mecha 'nism from the 'dash 16 of thevehicle, I have provided an upwardly extending shaft 24, thelowerendofwhich is connected to the screw 18 while with a bevel gear 25, whichgear is engaged by another gear 26 on the end of the shaft 27, thelatter leading through a tube 28 and through the dash 16 to the insideof the ve- On the end of this shaft I have mounted an operating key 29by the manip ulation of which the screw 18 may be actuated. I

In order to provide means for incasing this operating mechanism andlocking the same so that it cannot be tampered gwith'by unauthorizedpersons, I have provided a metal casing 30 which-has anupwardly-extending portion 31 for inclosing the gears and 26 and alsohas a laterally-extending portion 32 which has a separate portion 33embracing the manifold 13 and which separate portion is secured by alock 34 to the main casing 30. The screw-carrying frame 17 is secured'to this casing and the tube 28through which the horizontal shaft 27passes is also secured to this casing as it is threaded at one end 35and provided with lock nuts 36 both on the inside and on the PatentedJune 7, 1921.

and when it is desired to rethe upper end is provided i outside .of thiscasing, to bind its wall between them. tube is also threaded and issecured to the dash 16' by the two lock nuts 38.

In order to prevent the key 29 from being door to which is secured I toleave the vehicle and lock the same sothat it cannot be .used, it isonly necessary to open the casing key 29 which causes thestop;

When the ownerreturns'it is only necessary to unlock the casing 39, rotate the key 29to raise the stopm'ember 23 from engagement with the lever 14 leavin thecarbureter free to be manipulated as be ore.

-, The device is'extremely simple and practical in construction andeffective in its operation and by its use acar is securely lockedagainst theft.

The foregoing description is directed solel toward the constructionillustrated, but desire it to be understood that I reserve the privilegeof resorting to all the mechanical changes to which the device issusceptible, the invention being defined and limited only by the termsof the appended claims.

I claim:

1. In a device of the character described, the combination with acarbureter having 'a shut-0E valve to the intake manifold provided withan operating lever, of a screwoperated stop-member adapted to be movedto engage and lock said lever in closed powith said valve-lever to lockor release thesame, and means whereby said screw is adapted to'beoperated from the dash ofthe vehicle to which the mechanism is attached.

3. In a motor vehicle having a carbureter with ashut-ofi' valve to theintake manifold provided with an operating lever, the combination with astop-member, a screw positioned to move said stop into and out ofengagement with said lever to lpck, or release the same, means wherebysaid screw may be operated from the vehicle dash, and a casing inclosingand adapted to be locked about said operating mechanism to prevent itsbeing tampered with. In testimon whereof I aflix m signature.
